The pin 1 may have a slot 2 for bone tissue to grow into and a hole 3 to accommodate a securing screw. The crown 7 has its lateral walls 9 split into portions which are deformed during surgery to tightly embrace the articular process of the scapula. Each portion may carry a tongue (15), Fig. 3 (not shown) to assist in gripping the scapula, and the portions may be perforated by holes 10 into which bone tissue may intrude. Screw holes (14), Fig. 2 (not shown) receive screws to fix the crown to the scapula and a flute (12) in the top of the crown accommodates the tendon of the long head of the brachial biceps muscle.
